Betelgeuse, one of the biggest and brightest stars in the night sky, will momentarily vanish as an asteroid passes in front of it to produce a one-of-a-kind eclipse.

Betelgeuse is one of the brightest stars in Earth’s night sky, so its dimming – which lasted for a few months – was noticeable through observatories and backyard telescopes alike.

Betelgeuse, one of the brightest stars in the sky, may have a secret sunlike companion that drives the star’s mysterious six-year-long "heartbeat," new research suggests.

Binoculars and small telescopes will enhance the view. A light-year is 5.8 trillion miles. Betelgeuse is thousands of times brighter than our sun and some 700 times bigger.

The red supergiant Betelgeuse, a colossal star in the Orion constellation, experienced a massive stellar eruption -- the likes of which have never been seen before, according to astronomers.
